Former world boxing champ John Ruiz opens MMA/Boxing gym


Two-time World Boxing Association (“WBA”) heavyweight champion John “The Quietman” Ruiz has opened Quietman Sports Gym, inside of Gold’s Gym in Medford (4000 Mystic Valley Parkway), which is a suburb of Boston and only a few miles from where Ruiz grew-up in Chelsea.

Quietman Sports Gym is a full-contact gym, featuring a boxing ring as well as a cage for MMA, wrestling, jiu-jitsu and Muay Thai fighting. The gym also offers boxing and full-contact fighting classes, personal and semi-private instruction, self defense classes, and white collar boxing. The gym is also available for rentals on Sundays.

Ruiz is the owner and chief boxing instructor. Other instructors include John’s brother, Eddie Ruiz, and Jose “Raul” Sanchez for boxing; Miguel Rivera, MMA/Brazilian Jiu-Jitsu; Michael Matulonis, kickboxing; Rich Bloom, wrestling; NiccKossivas, Muay Thai/MMA striking.

“I grew up in this area and wanted to return to my roots in order to give back to these communities,” Ruiz explained. “I’m very close to my family and friends I have back here, so this is also an opportunity for me to spend more time with them. I believe a gym like this helps communities and children. Our goal is to create a gym that develops Olympians, but also give kids a place to go, just like I had at the Somerville Boxing Club, where they stay off the streets and learn how to box, wrestle or mixed martial arts training. There are so many bad temptations today for kids and many of them really need a place to go. We want to help them develop self-esteem and character.”

Future plans call for Quietman Sports Gym to become a sanctioned USA Boxing gym. Ruiz also wants to become a boxing and MMA promoter – professional and amateur – and he has already started a boxing consulting agency, Quietman Sports, along with his longtime attorney and advisor, Boston Attorney Anthony M. Cardinale.

“I was able to see the world because of boxing and I want to help kids do the same as part of our future ‘Quietman’ traveling team,” John added. “I’ve been fortunate to have had so many memorable times through boxing and I really want to pass along those experiences and what I’ve learned.”

The 39-year-old Ruiz, who lives in Las Vegas, retired from the ring a year ago. He had a 44-9-1 (30 KOs) career record and fought in 12 world title fights.

I think you guys are missing the point. This is an mma gym near a working class/working poor community and it'll help give kids who normally can't travel/afford mma training a place to go! War Ruiz

NO STONEY!! when I went to Somerville boxing club Stoney was the man. At that club. When the old boxing club closed. They opened one near grocery store but there were no trainers but a cool place to hit the bags.

 If Ruiz is coaching expect a bunch of New England fighters replacing wall and stall and lay and pray with jab and grab. It's cool to see a former HW champion (although Golota beat him and got jobbed in the decision) open a dual purpose boxing and MMA gym.  His style may have been ugly, but he did what worked for him and was successful. He wasn't the fastest, the hardest puncher, didn't have the prettiest technique, the best defense, the best offense and still managed to be a multi time champ with wins over guys who on paper were lightyears ahead of him by being smarter and working his gameplan.

I was there when he fought David Haye. The English fans, being largely scumbags, booed him on the way in.Nobody booed him on the way out.Really cool to see a boxer embracing the other combat sports.

Whatever his faults, he redeemed himself in his courageous effort against Haye.

didn't he make like 5 different lawsuits or requests for the boxing commission to give him immediate rematches?

This is my favorite Ruiz fight: a fan of the guy's boxing style, but he's obviously skilled - and the fact that he's opening an MMA gym is very cool.

depending on how involved he actually is with the training, you could learn some insane hand skills & stand up in that place really fast.
